What are the pins on a motherboard?

If your laptop has dead RAM slots, refuses to boot, or has connectivity issues, it might indicate bent or broken motherboard pins. Sometimes, motherboards are shipped from the manufacturer with bent CPU pins. If you inserted a CPU on top of already bent pins, the pins may bend further or break. Depending on the pin density, the pins may be able to be bent back into position. However, keep in mind that bending a pin can cause it to break.

To check for bent or broken motherboard pins, use the following instructions.

  1. Turn off your computer and remove the power cord from the power supply. Additionally, disconnect all other cables like USB cords.
  2. Open your laptop’s case using your specific laptop’s motherboard replacement guide, which can be found on your specific laptop’s device page.
  3. Using a flashlight, visually inspect the pins on the motherboard for any bent or broken ones.

If the pin is just slightly bent, it may not be necessary to straighten the pin, if a connection can still be completed. Sometimes, attempting to bend a pin back into place can result in further damage.

If a bin is broken, check a diagram of your exact motherboard to figure out whether or not the pin is essential. Motherboards include lots of pins, and there is a chance that your computer will function normally with just a couple of broken pins.

In general, broken pins are nearly impossible to replace. If the broken pin is essential to the normal functioning of your computer, you may need to replace the computer’s motherboard. To replace your laptop’s motherboard, see the Computer Motherboard Replacement page.

A massive pc noob here. I was wondering what these types of connectors are used for and what could be used with them. Thanks

    Those are standard 0.10 inch pin headers. It can be anything. You have to find the motherboard's manual to really figure it out.

    I have a blog! And a list of guides I've posted

    Could be a 'HD audio' connector, as it kinda looks like it and has the right amount of pins in the right way.

    But as mentioned above, it can be damn near anything, including a debug connector.

    my guess is it's an internal USB 2.0 header, but it could also be an internal serial (com) port. if it's a prebuilt it could also be othe stuff like firewire, card readers, etc.  like @Mira Yurizaki said, check the manual.

    pinout is different for HD audio but if it's a prebuilt who knows:

    Looks like a standard USB 2.0 header honestly. Maybe for something like an SD card reader on the front of the case?

    I would have thought the same, but Front audio always has pin 7 missing:

    it is not audio, or is a usb 2 header or a com port also known as serial port, but we are guessing, tell us the model of the pc to know more

    How many pins are there in motherboard?

    The ATX 24-pin power supply connector is the standard motherboard power connector in computers today. The connector itself is a Molex 39-01-2240 connector, often called a Molex Mini-fit Jr.

    Is it OK to touch the pins on a motherboard?

    If you bend the pins on the Motherboard or older CPUs then it's pretty much broken. You could try and realign them but it's going to be tough. Don't touch the pins.

    What are the pins on a CPU called?

    A CPU socket uses hundreds, or even thousands of metal pins as contact points to allow power and data to be passed between the CPU and the motherboard. The pins can be located either on the socket – in the case of LGA or Land Grid Array sockets, or on the CPU – known as Pin Grid Array, or PGA sockets.
